VIENNA, AUSTRIA nnvronron GIVING ACCESS TO GAVITIES on THE ANIMAL AND HUMAN ony Application filed May 8, 1929, Serial No.

Inresearch and therapeutic work it is often desirable to provide for readyaccess to cavitiesin the animal and human bodies for a more or less long period of time. I

The object. of my invention is to provide a simple and efficient device of this character which can be readily applied to and eventually removed from an incision in the wall of the cavity hermetically closed to the outside and readily opened and expanded for observation or therapeutic purposes without causing any notable disturbances and anguish.

With this object in view my device consists of a sleeve of some impermeable yielding irresorbable material such as soft rubber and preferably of oblong transverse section such. sleevehaving secured to its outside and between its ends a flange of soft yielding irresorbable material, preferably of soft rubber; the outer end of such sleeve is provided with a readily removable closing device of any suitable or preferred construction and adapt-' ed to hermetically close the outer end of the sleeve. V 7 The annexed drawings show by way of example embodiments of my device.

Fig. 1 is a perspective view of the device without the closing device, Fig. 2 is a similar view with the closing device applied to the outer end of the sleeve; Fig. 3 is a perspectlve view of the device inthe open expanded state; Fig. 4 shows the device in transverse section 1 is a sleeve of some soft yielding irresorbable material such as soft rubber and 2eis a flange of. soft flexible material such as soft rubber secured to the outside of the sleeve and 3 is a closing device of any suitable construction adapted to hermetically closefthe outer end of the sleeve when applied thereto.

As shown inFig. 4 the outer edges 4 and 6 of the sleeve and the outer edge 5 of the flange 2' may be reinforced and rounded for preventing or reducing irritation of those parts of the body with which they come or may come into contact.

Assuming for example that the. device has to be applied to the abdominal cavity as shown in Fig. 4 the inner part of the sleeve 1 is inserted into the incision previouslymade, so that senacaaim in Austria May 25,'1928.-

its edge whichis preferably reinforced and rounded as shown at 6 is within the ;-peritoneum 9 while the flange 2 having reinforced mechanical means such as clamps as clearly shown in Fig. 2 of any suitable construction. The construction of such clamps does not form part of the present invention.

If it is desired to give access to the abdominal cavity it is only necessary to open the outer end of the sleeve by removing the clamp. or by cutting the cement and then to expand the sleeve whereupon the outer end of the sleeve may be kept expanded by any suitable means as clearly shown in Fig. 3.

'After finishing the inspection ortherapeutic work inside the abdominal cavity the outer end of the sleeve is released, so that the sleeve and the incision contract automatically and the outer end'of the sleeve is again closed hermetically. In any case the sleeve should lit the incision as closely as possible.

In order to finally close again the incisionthe sutures and the device are removed and v theincision is caused to naturally close in the manner usual in rncdiclne. The lnvention is applicable not only tothe abdominal cavity but also to other cavities 'of the animal and human body and is exceedingly useful in research and therapeutic Work. found by experiments that the device may be kept applied to the abdominal cavity of dogs without causing any particular trouble to them.

What I claim is: a

1. A: temporary closure for surgical incisions comprising a flange of soft, impermeable, irresorbable material adapted to be secured adjacent to said incision and provided with a narrow slit in registry therewith,- and a sleeve of soft, impermeable, yielding, irresorbable material projecting outwardly from said flange at said slit and normally It has been 7 held thereby in a collapsed, sealed condition, said sleeve being capable of being widened to present a much larger opening to render the interior of the incision accessible therethrouflh.

2. X temporary closure for surgical incisions comprising a flange of soft, impermeable, irresorbable material adapted to be secured adjacent to said incision and provided with a narrow slit in registry therewith, and

a sleeve of soft, impermeable, yielding, irresorbable material projecting in opposite directions from said flange at said slit, the inwardly extending portion of said sleeve being arranged to project into said incision,

andthe outwardly projecting portion thereof being normally held in a collapsed, sealed condition by said slit, and being capable of being widened to present a much larger opening to render the interior of the incision accessible therethrough.

In testimony whereof I have aflixed my sig nature.
